2016 GMC Vibration on highway

I am shopping for a new one ton truck for a new truck camper. We really like the looks and interior of the GMC double cab/long bed SLT. Took it for a test drive and it had a horrible vibration at 65-70 which I would normally attribute to flat spots on the tires from the truck sitting on the lot for 170 days and/or tire balancing. We decided to sleep on it and do a little research and found quite a few complaints online and some even brewing class action lawsuits.

Anyone else here experience this? Is this a big deal and old news or a just a minority of the owners experiences.

If it rules out GMC it only leaves my option as Ford as I am told the new RAM's rear suspension is not up to the task for a truck camper. ( the longer leaf spring ?? more squat??) I am not opposed to an F350 but seems it's gonna cost me more to get the creature comforts of a GMC or RAM SLT with Navigation.

2007.5 is the old body body style now.

2015 is a completely different truck, and frame.

The only problem I've heard about on the 2015/2016 is the bed floor supposedly has a "crown" to it.

I have the first year 2007.5 New body style GMC 2500HD. Remember hearing about this on some GMC forums. I suggest you check there. Or Google "frame beaming". No vibration on mine, I would try a different 3500HD on the same road as not all the trucks had the vibration.

Where ever you heard the Ram suspension is not up to the task you were told wrong. The payload of the ram I think is highest of the three and handles my camper and horse trailer great. I have air bags but those are primarily used for the horse trailer.

The vibration issue plagues both the Ram and the GMC trucks. This is because the frames are so rigid that they transfer any vibration to the cab. I would say that most of the vibration is coming from the tires being out of round or out of balance.

On second thought, are you looking at a SRW or DRW?
